Product Description:

The CSH01.1C-S3-ENS-NNN-MA1-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This control section is fitted to IndraDrive power units to execute axis commands, distribute encoder feedback, and exchange real-time data with higher-level PLCs inside automated machinery. By concentrating communication, analog conversion, and safety monitoring on a single plug-in card, it simplifies cabinet wiring for packaging, material-handling, and processing lines.

The unit integrates 2 differential ±10 V analog inputs that sample at 12-bit resolution for setpoint or sensor acquisition, and it mirrors these channels with 2 ±10 V analog outputs for drive or process feedback. Overall controller demand on the 24 V backplane is held to 7.5 W, so multiple cards can share the same low-current supply. For deterministic motion control, it relies on SERCOS III. The onboard RJ-45 8-pin port links to ring or line network topologies without external hubs. Encoders are powered from a dedicated 12 V source and may use IndraDyn S, HIPERFACE, EnDat 2.1, 1 Vpp, or 5 V TTL signal formats, letting the drive accept both absolute and incremental position data.

Machine safety is handled through an ENS sub-module that draws 6 W and uses a D-Sub 9 female connector. The I/O rails are referenced to 24 V DC, matching common field supplies. Each input path is limited to 24 V / 3 mA so light-curtain or emergency-stop circuits can be wired directly, while solid-state driver pairs can source up to 24 V / 0.5 A to relays or contactors. A separate safety relay channel is rated at 24 V DC and 1 A for feedback loops that need potential-free contacts. Supplementary modules contribute minimal load, with the MA1 logic section using 2 W and both the S1 digital expansion and S3 communication interface requiring only 1 W each, allowing predictable thermal behavior even in densely populated drive racks.
